Overview

Sodankylä Geophysical Observatory was established in 1913 by
Finnish Academy of
Science and Letters
to perform geophysical measurements and research based on the observation
results. Measurements of the Earth's magnetic field began on 1st January
1914. On 1st August 1997, the observatory became an independent research
department of the University of Oulu.

Location

The Sodankylä Geophysical Observatory is located at 67° 22′ N,
26° 38′ E, which is 130 km north of Rovaniemi and 7 km south of
Sodankylä,
in the middle of Finnish Lapland at the beautiful banks of the river Kitinen.

Observations and Data

The Sodankylä Geophysical Observatory performs continuous measurements of
the Earth's magnetic field, cosmic radio noise, seismic activities, and cosmic
rays. The observatory operates two ionospheric radars and plays an active role
in the scientific and technical research related to the EISCAT incoherent scatter
radar system. An innovative measurement is the tomographic imaging of a
2-dimensional cross-section of the ionosphere from northern Norway to southern
Finland. Altogether SGO runs measurements in 19 different locations from
southern Finland to Svalbard.

Local magnetograms and the latest
images from the All-Sky Camera are available in real time.
Latest results of most continuous measurements are easily available. Descriptions of measurements and
the recorded data can be found in the
Archive. The data of measurements carried out
by the Oulu Unit (seismic recordings and cosmic rays) can be found on the unit's
web pages.
